It can be seen that the difference between the second information set and the zeroth information set is that the second information set includes identification information and removal information of the RFID tags that have been put into the refrigerator and have been removed from the refrigerator.
以本次检测到所有箱门均关闭时获取的第一信息集合为例,根据第一信息集合可以生成第三信息集合。具体的,通过对比第一信息集合与第二信息集合,确定本次移出储藏室的食材对应的RFID标签,即标识信息仅在第二信息集合中存在的RFID标签,将本次移出所述储藏室的RFID标签的标识信息和移出信息添加到第一信息集合中,生成第三信息集合,其中,本次移出所述储藏室的RFID标签的移出信息包括该RFID标签被标记的移出状态和根据当前时间确定的移出时间。Taking the first information set obtained when it is detected that all box doors are closed this time as an example, the third information set can be generated according to the first information set. Specifically, by comparing the first information set and the second information set, the RFID tags corresponding to the ingredients removed from the storage room this time, that is, the RFID tags whose identification information only exists in the second information set, are determined. The identification information and removal information of the RFID tag in the storage room are added to the first information set, and a third information set is generated, wherein the removal information of the RFID tag removed from the storage room this time includes the marked removal state of the RFID tag and according to The move-out time determined by the current time.
在一些实施例中,冰箱还包括检测器,用于分别检测每个所述箱门的开关信号,根据检测到的开关信号记录所述箱门的开关状态,发送开关状态信息给控制器。In some embodiments, the refrigerator further includes a detector for detecting the switch signal of each box door respectively, recording the switch state of the box door according to the detected switch signal, and sending the switch status information to the controller.
在一些实施例中,当检测器检测到任意一个箱门的开启信号或者关闭信号时,发送最新的开关状态信息给控制器。控制器接收检测器发送的开关状态信息,根据接收到的开关状态信息分析用户对箱门的操作行为。当接收到的开关状态信息显示所有箱门的当前开关状态均为关闭状态时,确定所有箱门均被关闭。In some embodiments, when the detector detects an opening signal or a closing signal of any box door, the latest switch state information is sent to the controller. The controller receives the switch state information sent by the detector, and analyzes the user's operation behavior of the box door according to the received switch state information. When the received switch state information shows that the current switch states of all the doors are closed, it is determined that all the doors are closed.
在本申请实施例中,检测器具体可以通过检测磁敏开关、机械开关检测箱门的开关信号。In the embodiment of the present application, the detector can specifically detect the switch signal of the box door by detecting the magnetic sensitive switch and the mechanical switch.
在一些实施例中,上述目标标签包括第一目标标签,该第一目标标签是指标识信息仅在第一信息集合中存在的RFID标签。可以理解,用户在本次操作中首次将第一目标标签标识的食材放入到储藏室中。对于第一目标标签,确定其对应的目标放入时间为当前时间。In some embodiments, the above-mentioned target tag includes a first target tag, and the first target tag refers to an RFID tag whose identification information only exists in the first information set. It can be understood that, in this operation, the user puts the ingredients identified by the first target label into the storage compartment for the first time. For the first target tag, the corresponding target insertion time is determined as the current time.
在一些实现场景中,用户可能会将某RFID标签所标识的食材取出后不久再次放入到冰箱中,此时,若根据用户再次将该食材放入到冰箱时的时间对该食材的放入时间进行更新,则会记录错误的放入时间。In some implementation scenarios, the user may put an ingredient identified by an RFID tag into the refrigerator shortly after taking it out. If the time is updated, the wrong put time will be recorded.
为避免在本次操作所放入的食材为用户取出不久后再次放入的同一批食材时,导致记录到错误的放入时间,在另一些实施例中,控制器通过对比第一信息集合与第二信息集合确定是否存在第二目标标签,该第二目标标签是指标识信息在第一信息集合和第二信息集合中同时存在且在第二信息集合中被标记为移出状态的RFID标签。需要说明的是,在第二信息集合中还包括第二目标标签对应的移出时间。In order to avoid recording an erroneous insertion time when the ingredients put in this operation are the same batch of ingredients that the user has taken out and put in again shortly after, in other embodiments, the controller compares the first information set with the The second information set determines whether there is a second target tag, where the second target tag refers to an RFID tag whose identification information exists in both the first information set and the second information set and is marked as a removed state in the second information set. It should be noted that the second information set also includes the move-out time corresponding to the second target tag.
在根据当前时间确定第二目标标签对应的目标放入时间时,首先判断当前时间与第二目标标签对应的移出时间之间的时间差大于预设阈值,若当前时间与第二目标标签对应的移出时间之间的时间差大于预设阈值,则确定第二目标标签对应的目标放入时间为当前时间;若当前时间与第二目标标签对应的移出时间之间的时间差不大于预设阈值,确定第二目标标签对应的目标放入时间为上一次的放入时间。示例性的,预设阈值可以为2个小时。When determining the target insertion time corresponding to the second target tag according to the current time, first determine that the time difference between the current time and the removal time corresponding to the second target tag is greater than the preset threshold, if the current time and the removal time corresponding to the second target tag The time difference between the times is greater than the preset threshold, then it is determined that the target insertion time corresponding to the second target tag is the current time; if the time difference between the current time and the removal time corresponding to the second target tag is not greater than the preset threshold, it is determined that the first The target insertion time corresponding to the second target label is the last insertion time. Exemplarily, the preset threshold may be 2 hours.
由以上示例可知,如果用户在将某食材取出后的预设时间内将该食材重新放入到冰箱中,将不对该食材对应的放入时间进行更新,因此可以避免记录到错误的放入时间,提高冰箱自动获取食材放入时间的准确性。It can be seen from the above example that if the user re-inserts an ingredient into the refrigerator within the preset time after taking it out, the corresponding insertion time of the ingredient will not be updated, so it is possible to avoid recording the wrong insertion time. , to improve the accuracy of the refrigerator's automatic acquisition of the time when the ingredients are put in.
在一些实施例中,预先建立RFID标签与食材的对应关系,具体为RFID标签的标识信息与食材信息的对应关系,控制器通过RFID检测模块识别RFID标签的标识信息,再根据RFID标签的标识信息从前述对应关系中查找RFID标签对应的食材信息。In some embodiments, the corresponding relationship between the RFID tag and the food is pre-established, specifically the corresponding relationship between the identification information of the RFID tag and the food information, the controller identifies the identification information of the RFID tag through the RFID detection module, and then according to the identification information of the RFID tag Find the food information corresponding to the RFID tag from the aforementioned correspondence.
在一些实施例中,用户可以对RFID标签与食材的对应关系进行更新操作,如添加新的对应信息,或者修改某RFID标签对应的食材信息。其中,修改某RFID标签对应的食材信息,可以使得同一RFID标签先后用于标识不同的食材,可以提高RFID标签的使用灵活度。In some embodiments, the user can perform an update operation on the corresponding relationship between the RFID tag and the food item, such as adding new corresponding information, or modifying the food item information corresponding to a certain RFID tag. Among them, modifying the food material information corresponding to a certain RFID tag can make the same RFID tag used to identify different food materials successively, which can improve the flexibility of using the RFID tag.
在一些实施例中,RFID标签与食材的对应关系还称为关联关系。RFID标签对应的食材信息即为RFID标签关联的食材信息。In some embodiments, the corresponding relationship between the RFID tag and the food item is also referred to as an association relationship. The ingredient information corresponding to the RFID tag is the ingredient information associated with the RFID tag.
在一些实现场景中,用户在将某RFID标签移出冰箱后,对其关联的食材信息进行修改。当用户将经修改后的RFID标签再次放入到冰箱时,由于该RFID标签前后对应的食材信息不同,若不对该RFID标签对应的放入时间进行更新,则会记录到错误的放入时间。In some implementation scenarios, after the user removes an RFID tag out of the refrigerator, the user modifies the associated ingredient information. When the user puts the modified RFID tag into the refrigerator again, since the corresponding food information before and after the RFID tag is different, if the insertion time corresponding to the RFID tag is not updated, the wrong insertion time will be recorded.
对于上述场景,为避免由于RFID标签所对应的食材信息发生变化而记录到错误的放入时间,首先,在修改RFID标签对应的食材信息,为RFID标签的标识信息添加再次关联状态的标记,以表征该RFID标签当前对应的食材信息与过去对应的食材信息是不同的。其次,控制器在获取第一信息集合时,获取储藏室内每个RFID标签的标识信息,其中,在所述标识信息当前对应的食材信息与过去对应的食材信息不同时,所述标识信息携带有再次关联状态的标记,该再次关联状态即用于表征RFID标签当前关联的食材信息与上一次关联的食材信息不同,得到第一信息集合。进而,控制器可以通过判断各RFID标签的标识信息是否被标记了再次关联状态,来判定各RFID标签前后对应的食材信息是否不同。 然后,在对比第一信息集合与第二信息集合以确定目标标签时,遍历判断第一信息集合中各标识信息是否被标记为再次关联状态,确定标识信息在所述第一信息集合和第二信息集合中同时存在且在第一信息集合中被标记为再次关联状态的RFID标签为第三目标标签。对于第三目标标签,确定当前时间为第三目标时间对应的目标放入时间。For the above scenario, in order to avoid recording the wrong insertion time due to the change of the food information corresponding to the RFID tag, first, after modifying the food information corresponding to the RFID tag, add a re-association status mark to the identification information of the RFID tag to It indicates that the food information currently corresponding to the RFID tag is different from the food information corresponding to the past. Secondly, when acquiring the first information set, the controller acquires the identification information of each RFID tag in the storage room, wherein, when the food information currently corresponding to the identification information is different from the food information corresponding to the past, the identification information carries The flag of the re-association state, that is, the re-association state is used to indicate that the information of the food material currently associated with the RFID tag is different from the information of the food material that was associated last time, and the first information set is obtained. Furthermore, the controller can determine whether the corresponding food material information before and after each RFID tag is different by judging whether the identification information of each RFID tag is marked with a re-association state. Then, when comparing the first information set and the second information set to determine the target label, traverse and determine whether each identification information in the first information set is marked as a re-associated state, and determine whether the identification information is in the first information set and the second information set. The RFID tags that exist simultaneously in the information set and are marked as re-associated in the first information set are the third target tags. For the third target tag, it is determined that the current time is the target insertion time corresponding to the third target time.
由以上示例可知,当用户将关联了新的食材信息的RFID标签再次放入到冰箱时,将根据当前时间对该RFID标签所标识的食材的放入时间进行更新,可以避免记录到错误的放入时间,提高冰箱自动获取食材放入时间的准确性。It can be seen from the above example that when the user puts the RFID tag associated with the new ingredient information into the refrigerator again, the insertion time of the ingredient identified by the RFID tag will be updated according to the current time, which can avoid recording the wrong storage. It can improve the accuracy of the refrigerator's automatic acquisition of the time when the ingredients are put in.
在一些实施例中,根据目标标签和对应的目标放入时间显示/更新食材管理界面,从而使得食材管理界面中通过所述目标标签标识的食材的放入时间为所述目标标签对应的目标放入时间。In some embodiments, the ingredient management interface is displayed/updated according to the target tag and the corresponding target insertion time, so that the insertion time of the ingredient identified by the target tag in the ingredient management interface is the target insertion time corresponding to the target tag enter time.

示例性的,响应于用户对自定义区的点击,显示如图7所示的虚拟存储界面,在该虚拟存储界面中,显示有待分区存储的食材信息和可被分配的储藏室选项,以及相关功能控件,如“确定”、“取消”等等。用户通过操作虚拟存储界面中的控件,实现对自定义区中的食材进行分区存储。Exemplarily, in response to the user's click on the custom area, a virtual storage interface as shown in FIG. 7 is displayed, in which the information of the ingredients to be stored in the partitions and the storage room options that can be allocated are displayed, as well as related information on the virtual storage interface. Functional controls such as "OK", "Cancel", etc. By operating the controls in the virtual storage interface, the user realizes the partitioned storage of the ingredients in the custom area.
由上述实施例可知,上述实施例虽然可以实现对食材的分区管理,但用户需要逐一对冰箱中新增的每一个食材进行操作,冰箱对食材的智能化管理程度较低,用户体验感较差。It can be seen from the above embodiments that although the above embodiments can realize the partition management of ingredients, the user needs to operate each new ingredient in the refrigerator one by one. The intelligent management of the ingredients in the refrigerator is low, and the user experience is poor. .
为进一步提高冰箱智能化管理能力、提高用户体验,首先通过检测箱门的开关信号(包括开门信号和关门信号)获取箱门的开关状态(包括开启状态和关闭状态),然后根据箱门的开关状态变化情况确定目标操作箱门,即被用户操作的箱门,根据目标操作箱门确定 目标储藏室,最后将本次操作后储藏室内新增的食材归类到确定的目标储藏室,可见,该分区实现过程无需用户手动操作,实现了对食材的完全智能化管理。In order to further improve the intelligent management capability of the refrigerator and improve the user experience, firstly obtain the switch status (including the open status and the closed status) of the box door by detecting the switch signal of the box door (including the door opening signal and the door closing signal), and then according to the opening and closing status of the box door. The state change determines the target operation box door, that is, the box door operated by the user, determines the target storage room according to the target operation box door, and finally classifies the newly added ingredients in the storage room after this operation into the determined target storage room. It can be seen that, The partition implementation process does not require manual operation by the user, and realizes a fully intelligent management of ingredients.
在一些实施例中,冰箱还包括检测器,用于分别检测每个所述箱门的开关信号,根据检测到的开关信号记录所述箱门的开关状态,发送开关状态信息给控制器,所述开关状态信息中包括每个所述箱门最近两次的开关状态。In some embodiments, the refrigerator further includes a detector for detecting the switch signal of each box door respectively, recording the switch status of the box door according to the detected switch signal, and sending the switch status information to the controller, so that The switch state information includes the last two switch states of each of the box doors.
示例性的,通过记录箱门的在先状态(Oldstate)和在后状态(Newstate)记录箱门的开关状态变化过程,比如,当检测到箱门的开启信号时,记录箱门的在后状态为开启状态(Newstate=开启),在检测到该开启信号前记录的在后状态(关闭状态)自动更新为在先状态,接着,当检测到箱门的关闭信号时,记录箱门的在后状态为关闭状态(Newstate=关闭),在检测到该关闭信号之前的在后状态(开启状态)自动更新为在先状态。Exemplarily, by recording the previous state (Oldstate) and the subsequent state (Newstate) of the box door, the change process of the opening and closing state of the box door is recorded, for example, when the opening signal of the box door is detected, the subsequent state of the box door is recorded. For the open state (Newstate=open), the later state (closed state) recorded before the open signal is detected is automatically updated to the previous state, and then, when the closing signal of the box door is detected, the trailing The state is the off state (Newstate=off), and the subsequent state (on state) before the off signal is detected is automatically updated to the previous state.
在一些实施例中,当检测器检测到任意一个箱门的开启信号或者关闭信号时,向控制器发送开关状态信息,开关状态信息中包括每个箱门最近两次的开关状态,即前述在先状态和在后状态。In some embodiments, when the detector detects an opening signal or a closing signal of any box door, it sends switch status information to the controller, and the switch status information includes the latest two switch statuses of each box door, that is, the aforementioned in the The first state and the latter state.
示例性的,检测器发送给控制器的开关状态信息中各字段内容如下:Exemplarily, the content of each field in the switch status information sent by the detector to the controller is as follows:
在一些实施例中,控制器接收检测器发送的开关状态信息,根据接收到的开关状态信息分析用户对箱门的操作行为。为便于说明,本申请将被用户操作的箱门称为目标操作箱门,目标操作箱门即是指开关状态发生变化的箱门。具体的,如果箱门的在先状态为开启状态,在后状态为关闭状态,说明用户对该箱门执行了完整的开关操作,确定该箱门为目标操作箱门。In some embodiments, the controller receives the switch state information sent by the detector, and analyzes the user's operation behavior of the box door according to the received switch state information. For the convenience of description, in this application, the box door operated by the user is referred to as the target operation box door, and the target operation box door refers to the box door whose switch state changes. Specifically, if the previous state of the box door is the open state and the latter state is the closed state, it means that the user has performed a complete opening and closing operation for the box door, and the box door is determined as the target operation box door.
例如,根据上述示例性示出的开关状态信息所包含的内容可以确定,冷藏室门未***作,变温室门被开启但未被关闭,冷冻室被先被开启后被关闭,因此确定目标操作箱门为冷冻室门和变温室门。For example, according to the content contained in the switch state information exemplarily shown above, it can be determined that the door of the refrigerator compartment is not operated, the door of the changing compartment is opened but not closed, and the freezer compartment is first opened and then closed, so the target operation is determined. The door of the box is a freezer door and a variable temperature chamber door.
在本申请实施例中,检测器具体可以通过检测磁敏开关、机械开关检测箱门的开关信号。In the embodiment of the present application, the detector can specifically detect the switch signal of the box door by detecting the magnetic sensitive switch and the mechanical switch.
在一些实施例中,控制器,根据目标操作箱门确定目标储藏室,具体的,当目标操作箱门的数量为1个时,确定该目标操作箱门对应的储藏室为目标储藏室,当目标操作箱门 的数量为多个时,确定预设的虚拟储藏室为目标储藏室,例如图3所示实施例中的自定义区。In some embodiments, the controller determines the target storage room according to the target operation box door. Specifically, when the number of target operation box doors is one, the controller determines that the storage room corresponding to the target operation box door is the target storage room. When the number of target operation box doors is multiple, the preset virtual storage room is determined as the target storage room, for example, the custom area in the embodiment shown in FIG. 3 .
示例的,若根据箱门状态信息确定目标操作箱门为冷藏室门时,那么目标储藏室则为冷藏室。若根据箱门状态信息确定目标操作箱门包括冷藏室和冷冻室时,那么目标储藏室则为虚拟储藏室。For example, if it is determined according to the box door state information that the target operation box door is the refrigerating compartment door, then the target storage room is the refrigerating compartment. If it is determined according to the box door state information that the target operation box door includes a refrigerator compartment and a freezer compartment, then the target storage room is a virtual storage room.
在一些实施例中,检测器每检测到一个箱门的开启信号,便向控制器发送一次开关状态信息,直到检测到最后一个被开启的箱门的关闭信号,向控制器发送最后一个开关状态信息。控制器根据接收到的开关状态信息判断是否所有的箱门均已关闭,即判断是否所有箱门的在后状态均为关闭状态,在所有箱门均关闭后,指示与其连接的RFID检测模块识别所有储藏室内的所有RFID标签,以获取储藏室内每个食材对应的RFID标签的标识信息,得到第一信息集合。In some embodiments, every time the detector detects an opening signal of a box door, it sends switch status information to the controller until it detects the closing signal of the last box door that was opened, and sends the last switch status to the controller information. The controller judges whether all the box doors are closed according to the received switch status information, that is, whether all the box doors are in the closed state. All RFID tags in all storage rooms are used to obtain identification information of the RFID tags corresponding to each food item in the storage room to obtain a first information set.
控制器在通过RFID检测模块获取到第一信息集合后,可以将第一信息集合与第二信息集合进行比较,以确定本次操作放入冰箱和/或取出冰箱的食材,其中,第二信息集合是根据上一次检测到所有箱门均关闭时获取的标识信息生成的信息集合。After acquiring the first information set through the RFID detection module, the controller may compare the first information set with the second information set to determine the ingredients put into and/or taken out of the refrigerator in this operation, wherein the second information The set is an information set generated based on the identification information obtained when it was detected that all the doors were closed last time.
以上一次检测到所有箱门均关闭时获取的、包含所有RFID标识信息的第零信息集合为例,第二信息集合根据第零信息集合生成得到,具体的,将上一次移出冰箱的食材对应的RFID标签的标识信息添加到第零信息集合中,并标记为移出状态,得到第二信息集合。可见,第二信息集合与第零信息集合的区别在于,第二信息集合中包括曾经放入到冰箱,且,已经移出冰箱的RFID标签的标识信息。As an example, the zeroth information set containing all RFID identification information obtained when all the doors of the box were detected to be closed in the previous example, the second information set is generated according to the zeroth information set. The identification information of the RFID tag is added to the zeroth information set, and marked as the removed state, to obtain the second information set. It can be seen that the difference between the second information set and the zeroth information set is that the second information set includes identification information of RFID tags that have been put into the refrigerator and have been removed from the refrigerator.
以本次检测到所有箱门均关闭时获取的第一信息集合为例,根据第一信息集合可以生成第三信息集合,具体的,通过对比第一信息集合与第二信息集合,确定本次移出储藏室的食材对应的RFID标签,即标识信息仅在第二信息集合中存在的RFID标签,将本次移出所述储藏室的RFID标签的标识信息添加到第一信息集合中,并将其标记为移出状态,生成第三信息集合。Taking the first information set obtained when it is detected that all box doors are closed this time as an example, a third information set can be generated according to the first information set. Specifically, by comparing the first information set and the second information set, it is determined that this time The RFID tag corresponding to the ingredients removed from the storage room, that is, the RFID tag whose identification information only exists in the second information set, the identification information of the RFID tag removed from the storage room this time is added to the first information set, and its identification information is added to the first information set. Marking the removed state, a third set of information is generated.
在一些实施例中,控制器通过对比第一信息集合和第二信息集合,确定本次放入冰箱的食材对应的标签,即目标标签,并根据确定的目标标签及目标储藏室,显示食材管理界面,食材管理界面中,通过目标标签所标识的食材的存储位置为目标储藏室。其中,目标储藏室为目标操作箱门对应的储藏室或者预设的虚拟储藏室。在根据目标标签和目标储藏室显示食材管理界面时,将目标标签对应的食材信息加载在目标储藏室对应的食材展示区,例如,在目标储藏室为冷藏室时,将目标标签关联的食材信息(如黄瓜)展示在冷藏室对应的食材展示区,在目标储藏室为虚拟储藏室时,将目标标签关联的食材信息展示在虚拟储藏室对应的食材展示区,如图3中示出的自定义区。In some embodiments, the controller determines the label corresponding to the ingredients put into the refrigerator this time, that is, the target label, by comparing the first information set and the second information set, and displays the management of the ingredients according to the determined target label and the target storage room. interface, in the ingredient management interface, the storage location of the ingredient identified by the target tag is the target storage room. The target storage room is a storage room corresponding to the target operation box door or a preset virtual storage room. When the ingredient management interface is displayed according to the target label and the target storage room, the ingredient information corresponding to the target label is loaded into the ingredient display area corresponding to the target storage room. For example, when the target storage room is a refrigerator room, the ingredient information associated with the target label is loaded (eg cucumber) is displayed in the food material display area corresponding to the refrigerating room. When the target storage room is a virtual storage room, the food material information associated with the target tag is displayed in the food material display area corresponding to the virtual storage room, as shown in FIG. 3 . Definition area.
在一些实施例中,目标标签可以是第一目标标签,该第一目标标签是指标识信息在第 一信息集合和第二信息集合中同时存在且在第二信息集合中被标记为移出状态的RFID标签,用户通过本次操作将第一目标标签对应的食材再次放入到储藏室中。In some embodiments, the target label may be a first target label, where the first target label refers to a label whose identification information exists in both the first information set and the second information set and is marked as being removed in the second information set RFID tag, the user puts the ingredients corresponding to the first target tag into the storage room again through this operation.
在一些实施例中,上述目标标签还可以是第二目标标签,该第二目标标签是指标签信息在第一信息集合中存在、在第二信息集合中不存在的RFID标签,用户通过本次操作将第二目标标签对应的食材首次放入到储藏室中。In some embodiments, the above-mentioned target tag may also be a second target tag, and the second target tag refers to an RFID tag whose tag information exists in the first information set but does not exist in the second information set. The operation puts the ingredients corresponding to the second target label into the storage compartment for the first time.
在一些实施例中,用户可以通过操作食材管理界面对存储位置为虚拟储藏室的食材进行一键分区,避免逐一对每一样食材进行操作。In some embodiments, the user can perform one-key partitioning of the ingredients whose storage location is the virtual storage room by operating the ingredient management interface, so as to avoid operating each ingredient one by one.
具体实现中,在显示屏显示食材管理界面时,用户可以通过操作食材管理界面输入第一指令,例如点击虚拟储藏室对应的食材展示区的任意位置或者指定位置,或者,点击食材管理界面提供的指定功能控件等。控制器接收用户输入的第一指令,在食材管理界面的上层显示虚拟存储界面,在虚拟存储界面中展示有存储位置为虚拟储藏室的食材和对应的推荐储藏室,其中,每个食材对应的推荐储藏室是根据食材与储藏室的预设对应关系确定的。In the specific implementation, when the display screen displays the ingredient management interface, the user can input the first instruction by operating the ingredient management interface, for example, by clicking any position or designated position of the ingredient display area corresponding to the virtual storage room, or, clicking on the menu provided by the ingredient management interface. Specify function controls, etc. The controller receives the first instruction input by the user, displays a virtual storage interface on the upper layer of the ingredient management interface, and displays the ingredients whose storage location is the virtual storage room and the corresponding recommended storage room in the virtual storage interface. The recommended storage room is determined according to the preset corresponding relationship between the ingredients and the storage room.
示例性的,图8为本申请根据示例性实施例示出的一种用户界面,具体为一种示例性的虚拟存储界面。如图8所示,在该虚拟存储界面中,展示有虚拟储藏室的食材和对应的推荐储藏室。Exemplarily, FIG. 8 is a user interface shown in this application according to an exemplary embodiment, specifically an exemplary virtual storage interface. As shown in FIG. 8 , in the virtual storage interface, ingredients in the virtual storage room and corresponding recommended storage rooms are displayed.
在一些实施例中,预先获取食材与储藏室之间的预设对应关系表,根据该预设对应关系表,即可根据虚拟储藏室中的食材信息确定其对应的推荐储藏室,例如,虚拟储藏室中包括黄瓜,根据预设对应关系表中黄瓜对应的储藏室是冷藏室,则在虚拟存储界面中显示黄瓜对应的推荐储藏室为冷藏室。In some embodiments, a preset correspondence table between the ingredients and the storage room is obtained in advance, and according to the preset correspondence table, the corresponding recommended storage room can be determined according to the information of the ingredients in the virtual storage room. The storage room includes cucumbers, and according to the preset correspondence table, the storage room corresponding to the cucumber is a refrigerating room, and the recommended storage room corresponding to the cucumber is displayed as a refrigerating room in the virtual storage interface.
在显示屏显示虚拟存储界面时,用户可以通过操作虚拟存储界面输入第二指令,例如点击虚拟存储界面中显示的指定功能控件(如图8示出的“确定”控件)。控制器接收用户输入的第二指令,将虚拟储藏室中的食材的存储位置由虚拟储藏室修改为对应的推荐储藏室,进而,实现对虚拟储藏室中的食材的一键分区。完成一键分区操作后,虚拟储藏室中的食材将展示在推荐储藏室对应的展示区中。When the virtual storage interface is displayed on the display screen, the user can input a second instruction by operating the virtual storage interface, for example, by clicking a specified function control displayed in the virtual storage interface (the “OK” control shown in FIG. 8 ). The controller receives the second instruction input by the user, modifies the storage location of the ingredients in the virtual storage room from the virtual storage room to the corresponding recommended storage room, and further implements one-key partitioning of the ingredients in the virtual storage room. After completing the one-click partition operation, the ingredients in the virtual storage room will be displayed in the display area corresponding to the recommended storage room.
在另一些实施例中,虚拟存储界面中除展示与食材对应的推荐储藏室以外,还可以展示其他储藏室选项以供用户选择,以便实现对食材的个性化存储。In other embodiments, in addition to displaying recommended storage rooms corresponding to the ingredients, other storage room options may also be displayed for the user to select in the virtual storage interface, so as to realize personalized storage of the ingredients.
由以上实施例可知,通过检测箱门的开关信号确定判断用户是否操作箱门,并在箱门的开关状态发生变化时,根据箱门的开关状态情况确定目标操作箱门,在箱门全部关闭后,根据确定的目标操作箱门确定目标储藏室,最后将储藏室新增的食材归类到目标储藏室中,实现了对食材存储位置的自动识别,对食材的分区管理过程无需用户手动操作,提升用户体验。It can be seen from the above embodiment that whether the user operates the box door is determined by detecting the switch signal of the box door, and when the switch state of the box door changes, the target operation box door is determined according to the switch state of the box door, and the box door is completely closed. After that, the target storage room is determined according to the determined target operation box door, and finally the newly added ingredients in the storage room are classified into the target storage room, which realizes the automatic identification of the storage location of the ingredients, and the partition management process of the ingredients does not require manual operation by the user. , to improve the user experience.
本申请实施例提供一种食材管理方法,图9为本申请根据一示例性实施例示出的食材管理方法流程图,如图9所示,该方法可以包括:An embodiment of the present application provides a method for managing ingredients. FIG. 9 is a flowchart of a method for managing ingredients according to an exemplary embodiment of the present application. As shown in FIG. 9 , the method may include:

当检测到箱门的开启信号或者关闭信号时,记录箱门的最新开关状态,并确定箱门的开关状态发生变化。根据箱门的开关状态变化过程,可以确定被用户操作(开启和/或关闭)的目标操作箱门,其中,目标操作箱门是指开关状态发生变化的箱门,例如,由开启状态变化为关闭状态的箱门,或者由关闭状态变化到开启状态的箱门。When the opening signal or closing signal of the box door is detected, the latest opening and closing state of the box door is recorded, and it is determined that the opening and closing state of the box door has changed. According to the change process of the opening and closing state of the box door, the target operation box door that is operated (opened and/or closed) by the user can be determined, wherein the target operation box door refers to the box door whose switch state changes, for example, from the open state to A box door in a closed state, or a box door that changes from a closed state to an open state.
步骤902,根据所述目标操作箱门确定目标储藏室,所述目标储藏室为所述目标操作箱门对应的储藏室或者预设的虚拟储藏室。Step 902: Determine a target storage room according to the target operation box door, where the target storage room is a storage room corresponding to the target operation box door or a preset virtual storage room.
具体实现中,可以在目标操作箱门的数量为1时,确定目标操作箱门对应的储藏室为目标储藏室;在目标操作箱门的数量大于1时,确定预设的虚拟储藏室为目标储藏室。目标储藏室为用户本次操作箱门所放入冰箱的食材的存储位置。In a specific implementation, when the number of target operation box doors is 1, the storage room corresponding to the target operation box door may be determined as the target storage room; when the number of target operation box doors is greater than 1, the preset virtual storage room may be determined as the target storage room. The target storage room is the storage location of the ingredients put into the refrigerator by the user operating the box door this time.
步骤903,当所有箱门的开关状态均变化到关闭状态后,获取第一信息集合,所述第一信息集合包括所述储藏室内每个食材对应的RFID标签的标识信息。 Step 903 , when the switch states of all the box doors are changed to the closed state, obtain a first information set, where the first information set includes identification information of the RFID tag corresponding to each ingredient in the storage room.
通过RFID检测模块识别冰箱内每个RFID标签的信号,以获取RFID标签的标识信息,获取到的每个RFID标签的标识信息形成第一信息集合。The signal of each RFID tag in the refrigerator is identified by the RFID detection module to acquire the identification information of the RFID tag, and the acquired identification information of each RFID tag forms a first information set.
步骤904,对比所述第一信息集合与第二信息集合,确定放入所述储藏室的目标标签,所述第二信息集合为根据上一次检测到所有箱门的开关状态均变化到关闭状态后获取的标识信息生成的信息集合。 Step 904, compare the first information set and the second information set, and determine the target label to be put into the storage room, and the second information set is to change to the closed state according to the last detection of the switch states of all the doors The information collection generated by the identification information obtained later.
目标标签包括第一目标标签和第二目标标签,第一目标标签是指标识信息在第一信息集合和第二信息集合中同时存在且在第二信息集合中被标记为移出状态的RFID标签,可以理解,第二目标标签在本次操作前被移出冰箱,通过本次操作再次被放入冰箱。第二目标标签是指标识信息仅在所述第一信息集合中存在的RFID标签,可以理解,第二目标标签为通过本次操作首次被放入冰箱的RFID标签。The target tag includes a first target tag and a second target tag, and the first target tag refers to an RFID tag whose identification information exists in the first information set and the second information set at the same time and is marked as a removed state in the second information set, It can be understood that the second target label is removed from the refrigerator before this operation, and is put into the refrigerator again through this operation. The second target tag refers to an RFID tag whose identification information only exists in the first information set. It can be understood that the second target tag is an RFID tag that is put into the refrigerator for the first time through this operation.
步骤905,显示食材管理界面,所述食材管理界面中,通过所述目标标签标识的食材的存储位置为所述目标储藏室。 Step 905 , displaying an ingredient management interface. In the ingredient management interface, the storage location of the ingredient identified by the target label is the target storage room.
图3示例性示出了一种食材管理界面中,如图3所示,在食材管理界面中,每个储藏室对应一个食材展示区,用于展示相应储藏室中的食材信息。FIG. 3 exemplarily shows an ingredient management interface. As shown in FIG. 3 , in the ingredient management interface, each storage compartment corresponds to an ingredient display area for displaying ingredient information in the corresponding storage compartment.
在步骤905中,根据目标标签和目标储藏室显示食材管理界面,具体是将目标标签对应的食材信息加载在目标储藏室对应的食材展示区中进行展示。In step 905, an ingredient management interface is displayed according to the target tag and the target storage room, and specifically, the ingredient information corresponding to the target tag is loaded into the ingredient display area corresponding to the target storage room for display.
例如,将一个或者多个目标标签对应的食材信息展示目标储藏室对应的食材展示区, 所述目标储藏室可能是冷藏室、冷冻室等中的一个,也可能是虚拟储藏室。For example, the food material information corresponding to one or more target tags is displayed in the food material display area corresponding to the target storage room, and the target storage room may be one of a refrigerator room, a freezer room, etc., or a virtual storage room.
图3为本申请根据示例性实施例示出的一种用户界面,其具体为一种示例性的食材管理界面。参阅图3,该食材管理界面被分割成左右两个显示区域;其中,左侧区域包括RFID标签识别控件和与各个食材类别对应的食材展示区,如水果类、蔬菜类,每个食材展示区中显示有相应类别的食材图标和食材名称;右侧区域包括推荐菜谱控件和与各个储藏室对应的食材展示区,如冷藏室、变温室、冷冻室等,每个食材展示区中显示有相应的食材图标和食材名称。FIG. 3 is a user interface shown in the present application according to an exemplary embodiment, which is specifically an exemplary ingredient management interface. Referring to Figure 3, the ingredient management interface is divided into left and right display areas; wherein, the left area includes RFID tag identification controls and ingredient display areas corresponding to each ingredient category, such as fruits, vegetables, and each ingredient display area. The corresponding categories of ingredients icons and ingredient names are displayed in the display; the right area includes the recommended recipe controls and the ingredient display areas corresponding to each storage room, such as the refrigerator room, changing room, freezer room, etc. Each ingredient display area displays corresponding ingredient icon and ingredient name.
在上述实施例中,通过将食材种类和/或食材名称转换成相应的食材编码写入到RFID标签中,实现RFID标签与食材的关联。例如,将RFID标签放置在读写设备的指定区域,接收用户在相应的操作界面输入的食材种类和/或食材名称,将用户输入的食材种类和/或食材名称转换为食材编码后写入到RFID标签中。该关联方式不但操作繁琐,而且食材编码一旦写入将无法更改,导致RFID标签的使用灵活性较差,且若操作错误将无法恢复。In the above embodiment, the association between the RFID tag and the food is realized by converting the type and/or name of the food into the corresponding code of the food and writing it into the RFID tag. For example, place the RFID tag in the designated area of the read-write device, receive the type and/or name of the ingredient input by the user on the corresponding operation interface, convert the type and/or name of the ingredient input by the user into the code of the ingredient and write it into the RFID tags. This association method is not only cumbersome to operate, but also the ingredient code cannot be changed once written, resulting in poor flexibility in the use of the RFID tag, and it cannot be recovered if the operation is wrong.
为解决上述问题,在一些实施例中,通过建立RFID标签与食材信息之间的对应关系,实现RFID标签与食材信息之间的虚拟关联,而无需针对每个RFID标签执行写入食材信息的操作,且可以通过修改RFID标签与食材信息之间的对应关系,使得同一个RFID标签先后与不同的食材信息相对应,提高RFID标签的使用灵活性。In order to solve the above problems, in some embodiments, by establishing the corresponding relationship between the RFID tag and the food material information, the virtual association between the RFID tag and the food material information is realized, and the operation of writing the food material information does not need to be performed for each RFID tag. , and the corresponding relationship between the RFID tag and the food information can be modified, so that the same RFID tag corresponds to different food information successively, and the flexibility of the RFID tag can be improved.
需要说明的是,建立RFID标签与食材信息之间的对应关系的方式有多种,以下将给出几种具体实现方式。It should be noted that there are many ways to establish the corresponding relationship between the RFID tag and the food material information, and several specific implementation ways will be given below.
在一些实施例中,预先建立RFID标签的标识信息与食材信息的对应关系,实现RFID标签与食材的虚拟关联。其中,RFID标签的标识信息可以为检测模块识别到的RFID标签的标签编码,也可以是标签编码中的一个码段。在这些实施例中,冰箱控制器根据每个RFID标签的标识信息和预先建立的对应关系确定每个RFID标签对应的食材信息。In some embodiments, the corresponding relationship between the identification information of the RFID tag and the food material information is established in advance, so as to realize the virtual association between the RFID tag and the food material. The identification information of the RFID tag may be the tag code of the RFID tag identified by the detection module, or may be a code segment in the tag code. In these embodiments, the refrigerator controller determines the food item information corresponding to each RFID tag according to the identification information of each RFID tag and the pre-established corresponding relationship.
示例性的,预先建立的RFID标签的标识信息与食材信息的对应关系可以如下表所示:Exemplarily, the pre-established correspondence between the identification information of the RFID tag and the food material information may be shown in the following table:
RFIDRFID | 食材信息food information |
标识1Logo 1 | 苹果、水果类apples, fruits |
标识2Logo 2 | 黄瓜、蔬菜类cucumbers, vegetables |
标识3Logo 3 | 猪肉、肉类pork, meat |
……... | ……... |
在上述实施例中,通过建立RFID标签的标识信息与食材信息的对应关系,实现RFID标签与食材的虚拟关联,无需针对每个RFID标签进行信息写入操作,只需要在获取到RFID标签的标识信息后,将标识信息与指定的食材信息对应保存在数据库中即可。并且,可 以通过修改该对应关系使同一RFID标签先后与不同的食材关联,解决食材信息一旦写入将无法更改的问题,提高对RFID标签的使用灵活性。In the above embodiment, by establishing the corresponding relationship between the identification information of the RFID tag and the food material information, the virtual association between the RFID tag and the food material is realized, and there is no need to perform an information writing operation for each RFID tag, but only after the identification of the RFID tag is obtained. After the information is obtained, the identification information and the specified ingredient information can be stored in the database correspondingly. In addition, by modifying the corresponding relationship, the same RFID tag can be associated with different food materials successively, which solves the problem that the food material information cannot be changed once written, and improves the flexibility of using the RFID tag.
在一些实施例中,在服务器侧建立RFID标签的标识信息与食材信息的对应关系表并发布。在冰箱侧,由控制器从服务器获取该对应关系表并保存在本地;当需要在用户界面中显示冰箱内通过RFID标签标识的食材时,控制器指示RFID检测模块检测冰箱内RFID标签的信息以获取RFID标签的标签编码,并从标签编码中解析出RFID标签的标识信息,再根据本地保存的对应关系表确定与RFID标签的标识信息对应的食材信息,最后根据与与RFID标签对应的食材信息显示用户界面。In some embodiments, a corresponding relationship table between the identification information of the RFID tag and the ingredient information is established on the server side and published. On the refrigerator side, the controller obtains the corresponding relationship table from the server and saves it locally; when it is necessary to display the ingredients identified by the RFID tag in the refrigerator in the user interface, the controller instructs the RFID detection module to detect the information of the RFID tag in the refrigerator to Obtain the tag code of the RFID tag, and parse the identification information of the RFID tag from the tag code, and then determine the food material information corresponding to the identification information of the RFID tag according to the locally stored correspondence table, and finally according to the food material information corresponding to the RFID tag Display the user interface.
